CVE-2020-14499
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAdvantech iView, versions 5.6 and prior, has an improper access control vulnerability. Successful exploitation of this vulnerability may allow an attacker to obtain all user accounts credentials.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceAdvantech iView versions 5.6 and prior contains an improper access control vulnerability that allows unauthenticated attackers to retrieve all user account credentials. The vulnerability likely stems from an unprotected API endpoint or page that returns sensitive user data without proper authorization checks.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify if Advantech iView is installedSearch the system for Advantech iView installation directories or check running services for iView processes. Look for web server configurations serving iView applications.Affected if Advantech iView software is present on the system
-
Determine the installed iView versionAccess the iView web interface and navigate to the About or Version page, or check the installation directory for version information files. Compare the version number to the affected range <= 5.6.Affected if The installed version is 5.6 or lower
-
Locate the iView web interface endpointIdentify the base URL of the iView application, typically accessible via HTTP/HTTPS on ports 80, 443, or a custom port. Note the application URL path for testing.Affected if The iView web interface is accessible over the network
-
Test for unauthenticated access to user credential endpointSend an HTTP GET request to common API endpoints such as /api/users, /api/credentials, /userlist, or similar paths that may return user account data without providing any authentication credentials.Affected if The endpoint returns user account data or credentials without requiring authentication
-
Verify sensitive data exposureInspect the HTTP response from unauthenticated endpoint tests. Check if the response contains usernames, passwords (in plaintext or hashed), or other credential-related information.Affected if The response includes user account credentials or sensitive user data without authentication
If Advantech iView version 5.6 or lower is installed and an unauthenticated API endpoint returns user credentials, the environment is affected by CVE-2020-14499.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor-supplied patch or upgrade to a version beyond 5.6. If no patch is available, consider network segmentation to limit exposure and monitor for unauthorized access to user credential endpoints.
